Numerical Simulation for Droplet Combustion Using Lagrangian Hydrodynamics [PDF]

, 1983
A predictive model of spray combustion must incorporate models for the wide variety of physical environments in a practical combustor. In regions where droplets are closely spaced, combustion resembles a diffusion flame; where they are well separated, an

Improved combustion stability of biogas at different CO2 concentrations using inhomogeneous partially premixed stratified flames

Global Energy Interconnection
Biogas is a renewable and clean energy source that plays an important role in the current environment of low- carbon transition. If high-content CO2 in biogas can be separated, transformed, and utilized, it not only realizes high-value utilization of ...

Investigation of Waste Biogas Flame Stability Under Oxygen or Hydrogen-Enriched Conditions

Energies, 2020
Increasing production rates of the biomethane lead to increased generation of waste biogases. These gases should be utilized on-site to avoid pollutant emissions to the atmosphere.

A Fuzzy Synthetic Evaluation Method of Flame Stability Based on Time–Frequency Analysis and Higher-Order Statistics

Energies, 2019
The flame combustion processes involves chemical reactions and therefore flame stability is difficult to accurately assess. Based on flame radiation measuring parameters, a new synthetic evaluation system of flame combustion stability is established.

Effect of heat release on the spatial stability of a supersonic reacting mixing layer [PDF]

A numerical study of the stability of compressible mixing layers in which a diffusion flame is embedded is described. The mean velocity profile has been approximated by a hyperbolic tangent profile and the limit of infinite activation energy taken, which

Flame fronts in Supernovae Ia and their pulsational stability

, 2013
The structure of the deflagration burning front in type Ia supernovae is considered. The parameters of the flame are obtained: its normal velocity and thickness. The results are in good agreement with the previous works of different authors.

Stability of a premixed flame in stagnation-point flow against general disturbances [PDF]

Previously, the stability of a premixed flame in a stagnation flow was discussed for a restricted class of disturbances that are self-similar to the basic undisturbed flow; thus, flame fronts with corrugations only in the cross stream direction were ...
